This MediaSorter is not known to me. Also the AOSP sources don't contain this keyword. Therefore it may be added by the manufacturer. As the process-ID seems to be the same as the MtpServer is running on this would be my guess. You never mentioned your device and manufacturer.

Yes Android cares what is inside. The media database stores not only file-name path and size of a file but also meta-data like exif data for pictures or mp3 ID3 tags for mp3 files. Therefore if the media database encounters a known file type with unexpected data it might run into problems and crash. The first step of solving a problem is understanding it. Therefore I suggest to you to use ADB. What I wrote is still a theory unless you prove it via ADB. You can also check adb logcat while copying the files onto the device via e.g. MTP. You may see a crash report (stack trace) of the media db

| Aug 31, 2020 at 9:14 | comment | added | parachutingturtle | @Robert What could cause files not being added to the media database? I tried many different files. What do you mean by "because of a content"? Does Android care what's inside a file? None of the files I've tried are protected in any way AFAIK, and I have the right to use them. I guess I could go down the ADB rabbit hole, but I'm not seeing where it would lead me, how it'd fix anything. I don't need to personally "truly see" what's there, I need android to see it. | |

You should activate developer options and ADB. An ls via ADB is the only way to truly see the content of a directory on device. Check if the files you copy are really missing. because based on your description my guess would be that the files you upload can't be added to the media database (because of a content) and therefore are not visible to most apps and MTP/PTP.
